We can confidently say that Millie Bobby Brown was the most comfortable attendee at Milan Fashion Week [1]. The exceedingly stylish 14-year-old attended the Moncler Genius show on Feb. 20 wearing a head-to-toe puffer gown from the brand. The simple look — well, simple for essentially being a sleeping bag dress — was only accented with Moncler's logo on the front.

Though a daring look we might typically see on Rihanna [2], the Stranger Things [3] actress pulled it off with ease, accessorizing with Repossi jewels and bow flats. It was an event brimming with creativity, after all: Moncler's newly launched Genius Project [4] invites other designers and creative directors to create collections for the brand. The show Millie and other celebrities attended was the project's big debut. Ahead, get a closer look at the most comfortable gown we might ever lay eyes on.
